      tracing: Keep NMI watchdog from triggering when dumping trace · b892e5c8
      Steven Rostedt authored
      As ftrace_dump() (called by ftrace_dump_on_oops) disables interrupts
      as it dumps its output to the console, it can keep interrupts disabled
      for long periods of time. This is likely to trigger the NMI watchdog,
      and it can disrupt the output of critical data.
      
      Add a touch_nmi_watchdog() to each event that is written to the screen
      to keep the NMI watchdog from affecting the output.

      tracing/ring-buffer: Only have tracing_on disable tracing buffers · 499e5470
      Steven Rostedt authored
      As the ring-buffer code is being used by other facilities in the
      kernel, having tracing_on file disable *all* buffers is not a desired
      affect. It should only disable the ftrace buffers that are being used.
      
      Move the code into the trace.c file and use the buffer disabling
      for tracing_on() and tracing_off(). This way only the ftrace buffers
      will be affected by them and other kernel utilities will not be
      confused to why their output suddenly stopped.
